What does decorous mean?
"Decorous" is a formal adjective describing behavior, speech, or appearance that conforms to accepted standards of politeness, dignity, and good taste. A person who is decorous acts with restraint and respect for social convention — remaining composed at a solemn ceremony, addressing elders with measured courtesy, or dressing appropriately for an official occasion. The word derives from Latin "decorus," meaning seemly or beautiful, from "decus" (honor or ornament), which also gives us "decorum" and "decorate." In modern usage it appears chiefly in written English, journalism, and literary description, where it conveys quiet approval of proper conduct. It can, however, carry a subtle hint of stiffness, suggesting manners so correct they verge on the inhibited. Its natural opposites are "indecorous," "improper," and "unseemly." Knowing "decorous" allows a writer to praise tactful, dignified behavior with precision and elegance.

"Decorous" and "gorgeous" rhyme for a reason — both trace back to the same Latin word "decus," meaning beauty or honor; one kept the polish, the other the glamour.

Etymology of decorous
"Decorous" entered English in the early 17th century, borrowed from Latin "decorus," meaning "seemly, fitting, or beautiful." The Latin root "decus" means "honor, ornament, or distinction," and also underlies related borrowings such as "decorum" (via Latin "decor") and "decent." The same root family produced "decorate" and its derivatives, all sharing the sense of that which adorns or befits. Cognate forms appear across Romance languages, such as French "décor."
